Since Loki has started going outside, there seems to be an increasing number of tom cats appearing in my garden. There is the grey and white one, who I think Loki quite likes, they tend to just sit there a couple of metres apart staring at eachother, I haven't seen any hostility. The black and white one, who is aggressive, and I have caught fighting with both Annie and Loki. Well not fighting, but yowling and intimidating. Loki just rolls over. : Today there was a big fat tabby (with a lovely purple collar ) who I've never seen before. He actually looked a bit like wild cat, very pretty. Don't know what he was doing, as Loki was up the end of the garden not near him. I'm not sure which if any of them are neutered, or who they belong to. Are they checking out the garden because of Loki? He was neutered at 5 months. I doubt it, but is there any way to deter them?
